Choke valves
Choke valve falls into positive choke valve, needle choke valve, plunger type choke valve, cage choke valve and orifice plate choke valve. The materials of the body and components of choke valve are completely in conformity with API 6A and NACE MR-0175 Standard Specifications, and it is widely used for onshore and offshore petroleum drilling. Our choke valves are supplied in two types: Positive and Adjustable.
Structural features:
With opening indicator
Structural design based on relief valve
Structural design based on plane thrust bearing
Metal-to-metal seal design
Lip packing sealing valve stem made of special materials
Made of high wear-resistant materials, so that choke valve trim and grease fitting can endure abrasion and corrosion effectively
Design and manufacturing is in strict accordance with API Spec 6A, ANSI and NACE MR-0175 Standard.
